ABSTRACT:
A folding sofa bed frame structure has a TV control link and an associated toothed ratchet element connected thereto, by which the rear end section of the structure can be selectively positioned in two differing "TV" positions. A cam portion on the ratchet element automatically effects disengagement from either TV position upon pivoting of the rear end section into a substantially perpendicular relation to the main intermediate section of the structure. The ratchet arrangement is effective to automatically engage into and disengage from either TV position without manual manipulation, other than manual lifting of the rear end section, and is automatically effective to disengage when the bed frame structure is folded into the sofa frame.
